BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to user authentication in contentdistribution and more particularly to identifying a user accessingdistributed content over a computer communications network.

2. Description of the Related Art

The growth of the Internet largely can be attributed to the desire forremotely disposed individuals to share content. Long before thedevelopment of the hypertext transfer protocol (HTTP) and the World WideWeb, academics, bureaucrats and private individuals indexed andexchanged content over the Internet. The explosion of Internet usefollowing the development of the World Wide Web, however, has resultedin a vast sea of content leading to creation by necessity of advancedcontent searching applications used almost universally by all users ofthe Internet today.

Content can be characterized as passive or active. Passive contentrefers to content able only to be perceived (viewed in a visual mode, orheard in an audible mode, by way of example) while active contentpermits user interactivity with the content. The venerable Web basedform represents a traditional form of interactive content in whichcontent is presented in a Web page along with one or more input fieldssuch as text input fields, radio buttons, check boxes, drop down boxes,and the like, into which an end user can provide information to bereceived and processed by back end programmatic logic.

In the case of a Web site providing passive content, oftentimes it isdesirable to customize the passive content or arrangement of the passivecontent in the Web site according to the identity of the end userviewing the Web site. For example, an e-commerce site might preferpresenting products known to be of interest to a viewing end user. Inthe case of a Web site providing active content, it is just as desirableto customize the interactions with the Web site, for example bypre-populating fields of a form with information known to be associatedwith an interacting end user. Of note, customization of Web site contentcan be provided in connection with the degree to which a viewing enduser is authorized to interact with particular content on the Web site.

Of note, irrespective of the passive or active nature of content in aWeb site, many Web sites provide for progressively different disclosuresof content based upon how certain a viewing end user can be identified.Also known as “step-up authentication”, a Web site utilizing step-upauthentication can attempt to identify an end user through the use ofcookies or flash files in which user credentials are stored, the manualprovision by the end user of credentials in a log-in screen, theprovision of a certificate, or the provision of biometric data, to namea few examples. Cookies and flash files also have proven helpful in thefield of Web site analytics in tracking the browsing behavior of the enduser in interacting with the content of a Web site.

However, cookies and flash files are limited to the relationship betweenthe computing device storing the cookie or flash file and the computingdevice used to attempt access to the secure content. Consequently, whenattempting access to a Web site from a computing device that differsfrom the computing device in which the cookie or flash file is stored,manual identification and authentication of the end user will berequired. Further, even where a single device is used both to store acookie or flash file and to access the Web site, many end usersfrequently direct the periodic removal of cookies and other temporaryfiles so as to require the later re-identification and authentication ofthe end user.

BRIEF SUMMARY OF THE INVENTION

Embodiments of the present invention address deficiencies of the art inrespect to user identification for Web site content access and provide anovel and non-obvious method, system and computer program product forinferred user identity in content distribution. In an embodiment of theinvention, a method for inferred user identity in content distributionincludes retrieving a set of data of a particular classification from adata store of a computing device of an unidentified user requestingaccess to content in a content distribution system. The method furtherincludes comparing the set of data of the particular classification toknown patterns of data of the particular classification corresponding todifferent known users. The method yet further includes inferring anidentity of the unidentified user based upon at least a partial matchingof the compared set of data of the particular classification and knownpatterns of data of the particular classification. Finally, the methodincludes managing user interactions of the unidentified user based uponthe inferred identity.

In one aspect of the embodiment, the particular classification ispreviously visited Web sites, and optionally previously visited Websites at particular times. In another aspect of the embodiment, theparticular classification is addresses of previously connectedcomputers. In yet another aspect of the embodiment, the particularclassification is previously locations of the computing device,optionally at particular times. Of note, managing user interactions ofthe unidentified user based upon the inferred identity can includetracking user behavior accessing content in the content distributionsystem in connection with the inferred identity. Alternatively, managinguser interactions of the unidentified user based upon the inferredidentity can include limiting access to content in the contentdistribution system according to the inferred identity.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

The accompanying drawings, which are incorporated in and constitute partof this specification, illustrate embodiments of the invention andtogether with the description, serve to explain the principles of theinvention. The embodiments illustrated herein are presently preferred,it being understood, however, that the invention is not limited to theprecise arrangements and instrumentalities shown, wherein:

FIG. 1 is a pictorial illustration of a process for inferred useridentity in content distribution;

FIG. 2 is a schematic illustration of a content distribution dataprocessing system configured in inferred user identity; and,

FIG. 3 is a flow chart illustrating a process for inferred user identityin content distribution.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the invention provide for inferred user identity incontent distribution. In accordance with an embodiment of the invention,a connection can be received for a content server distributing contentover a computer communications network from an end user at a computingdevice. A data store disposed within the computing device can beaccessed and data residing in the data store can be classified, forexample according to different locations of the computing device atparticular times, different Web sites visited through one or morecontent browsers of the computing device, or the identities of othercomputing devices to which the computing device has communicativelyconnected to previously. The classified data subsequently can beprocessed to infer an identity of the end user. Thereafter, the actionsof the end user can be managed in association with the inferred identitywithout requiring the use of cookies, flash files, manual authenticationor biometric identification methods. The management of the actions ofthe end user, for example, can include the recording of interactions bythe end user with content provided by the content server, or therestricting or permitting of access by the end user to content providedby the content server.

In further illustration, FIG. 1 pictorially shows a process for inferreduser identity in content distribution. As shown in FIG. 1, an end user160 can access a content distribution system 120 by way of a computingdevice 110 over computer communications network 130. User identityinference engine 150 can access the computing device 110 to retrievedata 140 of a particular classification, such as different locations ofthe computing device at particular times, whether set forth explicitlyby the computing device, or implicitly by associating the device with aparticular location of a cellular telephone tower, different Web sitesvisited through one or more content browsers of the computing device, orthe identities of other computing devices to which the computing devicehas communicatively connected to previously. Thereafter, the useridentity inference engine 150 can infer the identity of the end user 160by matching the data 140 of particular classification to a user in atable of known users 160. In this way, the identity of the end user 160can be inferred without requiring the use of cookies, flash files,manual authentication or biometric identification methods.

The process described in connection with FIG. 1 can be implemented in acontent distribution data processing system. In yet furtherillustration, FIG. 2 schematically shows a content distribution dataprocessing system configured in inferred user identity. As shown in FIG.2, a host computer 150 can be configured for communicative coupling todifferent computing devices 110 over a computer communications network140. The computing devices 110, which can include personal computers,personal digital assistants, mobile telephones, and computers embeddedas part of consumer appliances, to name a few examples, each can supportthe execution of one or more content browsers 120 and can include atleast one corresponding data store 130, such as a hard disk drive, flashmemory, solid state memory and the like.

The host computer 150 can support the execution of a content server 150configured to serve content over the computer communications network 140to requesting ones of the content browsers 120. Optionally, the contentbrowsing behavior of end users access content served by the contentserver 160 can be computed by analytics module 180A. As a furtheroption, in servicing requests from the content browsers 120, the contentserver 160 can control access to content served by the content server160 by way of an access control module 180B in accordance with anidentity of an end user requesting access to the content.

In support of the analytics module 180A and/or the access control module180B, a user identity inference module 170 can execute in memory by atleast one processor of the host computer 150. The user identityinference module 170 can include program code that when executed by thehost computer 150, can infer an identity of a user requesting access tothe content server 160 without requiring the use of cookies, flashfiles, manual authentication or biometric identification methods. Inthis regard, the program code can be enabled to respond to a request toaccess the content server 160 from a content browser 120 executing in acorresponding computing device 110 by retrieving data of a particularclassification from the corresponding computing device 110 and mappingthe data of the particular classification to a known user in a useridentity table 190.

For example a list of retrieved Web sites visited by the content browser120 at particular times of the corresponding computing device 110 can becompared to a known pattern of visited Web sites at particular times ofa known user in the user identity table 190. As another example, a listof previously connected computers (by way of IP address, for instance)at particular times can be compared to a known list of previouslyconnected computers at particular times of a known user in the useridentity table 190. As yet another example, a list of geographiclocations and particular times for the corresponding computing device110 can be compared to a known list of previous geographic locations andparticular times of a known user in the user identity table 190.

In even yet further illustration of the operation of the user identityinference module 170, FIG. 3 is a flow chart illustrating a process forinferred user identity in content distribution. Beginning in block 310,a request can be received from a computing device to access content at acontent server. In block 320, a communicative connection can beestablished with the computing device and in block 330 a data store inthe computing device can be selected as can a classification of interestfor data in the data store. In block 340, data according to the selectedclassification can be retrieved from the data store and in block 350 theretrieved data can be compared to known patterns of data associated withdifferent known users. In block 360 an identity of a user issuing therequest can be inferred based upon the comparison of known patterns.Further, a degree of confidence in the inference can be computedaccording to the degree to which the retrieved data compares to theknown patterns. Finally, in block 370 user interactions with the contentserver can be managed in respect to the inferred identity and computedconfidence, such as be limiting access by the user to particular contentprovided by the content server, or by tracking and analyzing contentbrowsing behavior of the user.
